They just might have figured that you had replaced the 15t with a 14t.
No, I screwed up the order myself.
My stock chain is shot, so I decided to replace the whole she-bang.
I'm really used to the stock configuration, so the closest ca-cycleworks can do is a 15t front and a 43 rear. Should be very little difference.
Oh, and the rear sprocket is one of those cool looking STEALTH jobbies
